Reference is occasionally made to "the crew," in which case it is a generalized statement meant to include everyone aboard the ship. A reference to "senior officers" would refer to a much smaller, specific group of the crew members.
Wish I had seen this sooner. That was exactly what I was trying to say about Spock, and apparently not making clear. When he says "officers," he means, essentially, the "department heads" plus Kirk, so he means Scotty, McCoy, etc. When he says "crew" he means everybody else, regardless of rank.
It makes sense to me that in this possible future, officers and enlisted work side by side and do the same jobs (up to a point). It does muddy the terminology between "officer" the ranks and "officer" the position. But what would be a better term for all those who serve onboard a star ship than "officers" or "crew"? Astronauts probable sounded to current, but they literally appear to work like "sailors" traveling the "stars" so I guess that would not be out of the question
